Design Principles¶

• All Arvados core components are free software.
• Any application can run on Arvados, including non-free tools that are only available as binaries. Use wrapper scripts around vendor-provided source and binary distributions, rather than maintaining derivative works.
• Use web technologies to tie components together, so programs can access Arvados regardless of programming language or framework.
• Use the best tool, programming language, or framework for each component, instead of standardizing on a single platform for the sake of conformity.
• Where possible, use established, widely understood components such as SSH, Git, Rails, and WebSockets rather than hand rolling custom components.
• Use technologies such as virtualization and Linux containers to increase portability and flexibility of deployment.
